Weeping Cedar [Need Advice]

Hello,

About 5 years ago I planted a Weeping Cedar in my front yard. Until about a year ago it was doing well (not growing as much as I would have hoped but still doing well). About a year ago it started losing needles. Now it's barely hanging in and I'm not sure what to do (I'm not really good with these things so I need some help).

I'm attaching some photos to give an idea of the issue and the area. The soil is moist and well drained.
